MACHINE FOR MAKING FUSES.

Specification of Letters Patent. Patented Dec. 14 1909.

Application filed August 1a, 1905. Sci-19.1110. 274,711.

To all whom it may concern:

Be it known that I, OHAnLns E. SCHMUNK, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Machines for Making Fuses, of which the following is a specification.

The object of my invention is to provide a new and improved fuse-making machine and to this end my invention consists, of a fuse-making machine, in the novel features of construction, and in the combination and arrangement of parts all as fully hereinafter described and claimed.

The presentinvention is particularl d;-

1n s o blasting-fuses. These blasting-fuses are commercially known as double-tape fuse, consisting of a fuse-core, fifteen strands of thread, and two windings of tape; singletape fuse, a fuse-core, twenty strands wound thereon, and one winding of tape; and cot ton-fuse, com rising the fuse-core and fifteen strands 0 threads wound thereon.

In the accompanying drawings, which illustrate an application of my invention, Figure 1 is a central vertical sectional view of a portion of the machine constructed in accordance with my invention; Fig. 2 a view similar to Fig. 1, showing the remaining portion of the machine; Fig. 3 a topplan showing part of the machine; and Fig. 4 a top-plan showing remaining portion of the-machine.

Referring to the drawings, the machine, as .illustrated and preferred, com rises a table 1, supported by legs 2.- The ta lenear one end is formed with an opening 3, and over this opening a casin 4 is located. This casing is preferably ma e in several parts secured together by bolts and the casing attached to the table.

Within the casing is a series of rotar 8-, 9 and 10. In the upper set 8, I preferably employ ten bobbins, and in the intermediate and lower sets 9 and 10, five bobbins each. Extending downwardly mto the casing and the carriers is a hopper 11, provided with a former or nozzle 12, and located adjacent tothe hopper and arranged to be drawn down through the ho per and former; over a small guiding-w eel 13 is a core-thread 14. The hopper 11 is desi ed to hold the material or materials, as t e core-thread 14 and a suitable explosive, which constitute the fuse-core of the fuse.

Extending lon itudinally up the machine 18 a driving-sha t 15. This shaft is supported by bearings 16 carried on upri hts 17, which latter are attached to the tab e 1. Shaft 15, as illustrated, is designed to be driven by a belt, not shown, which extends over a cone-pulley 18. On the forward end of shaft 15 I employ a gear 19. Gear 19 meshes with a gear 20, mounted on a wormshaft 21, and 22 designates a worm. Worm 22 meshes with worm-wheel 22 carried upon a transverse shaft 22*. Shaft 22 has also mounted thereon a drum 23. The function of this mechanism is to impart a rotary movement to the drum 23. The means just described constitute a reeling-mechanism for drawing the materials through the machine in the operation of forming the fuse. Mounted on the opposite end of shaft 15 is the main-driving pinion 24. Pinion 24 meshes with the upper gear-wheel 5 and the upper-face of intermedlate gear 7, and, as shown, is designed to revolve said gears 5 and 7 together with the two sets of bobbins carried on said gears, in opposite directions. Between the lower face of intermediate gear 7 and the lower gear 6 is an idler-gear 25. This idler 25 is mounted on a shaft 26 and is adapted to be shifted on said shaft for the purpose of throwing the lower-carrier 6 into and out of operation.

Attached to and extending downwardly from each rotary-carrier is a set of guidearms 27. The function of these guides is to guide the strands from the bobbins to the former 12.

The threads or strands from the several sets of bobbins are designated by the reference characters 8 9 and 10*.

Below the table and supported by a hanger 27 is a guide-pulley 28, over which the fuse-core and wound strands are drawn from the former. Also located below the table and supported by hangers 29 is a series of pitch-boxes or receptacles 30. Three of these itch receptacles are shown and each is pre erably of the form illustrated, that is to say, the receptacles are divided into com- 'partments a, b and c. The walls of the smaller compartments 6 and c are perforated for the purpose of permitting the passage of the fuse therethrough and also to permit the pitch contained in t e larger compartment a to enter said smaller compartments 6 and c. In practice, I prefer to emdploy a sponge d in each compartment b an 0, for the purpose of applying the pitch to the fuse.

Between the pitch-boxes are two tapewinding mechanisms, designed to cover the strands with one or two layers of tape. These mechanisms are supported from the table by means of hangers 31 and each comprises a pulley-wheel 32, mounted on a hub 33, a friction-clutch 34, the latter being operated by lever 35, and a tape-carrier 36. Tape-carrier 36 is hinged to hub 33 and is designed to revolve therewith. Secured to carrier 36 is a guide 37, through which the strands pass just-prior to being wound with the piece of tape 38. V v

38 designates a pulley formed on the tape-carrier.

Fig. 1 of the drawin shows the wheels, friction -clutch, etc., 0 the tape-winding mechanism in elevation, while in Fig. 2 I have shown this mechanism in section. The first tape-winding mechanism is driven by a straight-belt 39 and the second mechanism driven in an opposite direction b a crossedbelt 40. Belts 39 and 40 are riven from suitable pulleys carried on shaft 15. Beyond the last pitch-box is a receptacle 41, supported from a hanger 42. This receptacle is designed to hold a suitable powder through which the completed fuse is drawn before it reaches a pulley 43. Pulley 43 is employed to guide the finished fuse onto the drum 23.

While I have shown a preferred embodiment of my invention in the construction illustrated by the drawings, I do not desire to limit myself to that particular construction, for various modifications may be made in the construction illustrated without departing from the scope of my invention.

'VVith the machine described, I am enabled to produce any or all of the several kinds of blasting-fuses now so generally sold and heretofore mentioned, in an economical and satisfactory manner. I am further enabled to produce fuses differing in construction from those described by changing the number of bobbins carried by the rotary-carriers and by varying the number of tape-winding mechanisms.
